Perhaps you should try some spelling variations:
phuong danh » phuong anh, phuong hanh, phuong thanh
phuong dinh » phuong binh, phuong linh, phuong trinh
hien manh » hien hanh, tien manh, hieu manh
tranh cua » doanh cua, manh cua
cua thong » cua thuong, cua khong, cua tong
duong van » duong va, luong va, dang van
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien manh - canh tranh cua thong ((((phuong danh) OR (phuong dinh))) or (duong van)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien manh - canh tranh cua thong ((((phuong danh) OR (phuong dinh))) OR (duong van)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien manh - canh tranh cua thong ((((phuong danh) OR (phuong dinh))) or (duong van)) toan cau*".
